Foam Cutting Application

Cutting thick and soft sponge rings without deformation is a common challenge in foam processing industries.
Soft sponge materials are easy to compress, deform, tear, or collapse during manual cutting or low-precision processing.

Jinan M.RISE Machinery Equipment Co., Ltd. provides intelligent CNC oscillating knife cutting solutions designed for high-precision soft material cutting applications.

In this project, our customer required:

• 50mm thick soft sponge ring cutting
• OD60mm / ID54mm precision rings
• Clean vertical sidewalls
• No tearing or deformation
• Stable batch production consistency

Our M.RISE CNC Oscillating Knife Cutting Machine successfully achieved all customer requirements with smooth, accurate, and repeatable cutting performance.

Challenges of Cutting Thick Soft Sponge Rings

Many manufacturers experience problems when cutting thick soft sponge materials:

• Sponge deformation during cutting
• Uneven ring edges
• Rounded or collapsed sidewalls
• Material tearing
• Inconsistent ring dimensions
• Low manual cutting efficiency
• Poor batch consistency

Especially for small inner diameter sponge rings, maintaining clean inner edges and stable ring shape can be difficult with traditional cutting methods.

This is why more manufacturers are switching to CNC oscillating knife cutting technology.
